Hello fellows Oc,
I've look around for fans to best fit for radiator configuration and they all point to high "static pressure" fan. I don't agree with this but since it's me against a multi-billions dollar company, the doubt are in my part. From what i gathered:
high static pressure (SP): more blades, blades oriented slightly parallel to the fan face, "ideal for rads"
high air flow (AF): fewer blades, blades oriented slightly perpendicular to fan face, "ideal for case"
base on the blades angle, the air blown would be illustrated as below:

please excuse my crude drawing
If the picture shown is correct, then air pressure at any point in an AF should be higher (allow air to go around obstruction, like a rad) then the SP fan. Therefore it would make sense that AF should be chosen for rads. Additionally, AF fans have less rpm (equates to less noise) than SP.
Data I gathered:

Thanks,
